− | '''Milan''' is the codename | + | '''Milan''' is the codename of [[AMD]]'s {{amd|EPYC#7003 Series (Zen 3)|EPYC 7003 series}} of high-performance microprocessors based on the {{amd|Zen 3|l=arch}} microarchitecture for single- and dual-socket server platforms. Launched in March 2021 it succeeded the second generation of EPYC processors, the {{amd|EPYC#7002 Series (Zen 2)|EPYC 7002}} "{{\\|Rome}}" series.<ref name="pr20210315">[https://ir.amd.com/news-events/press-releases/detail/993/amd-epyc-7003-series-cpus-set-new-standard-as-highest "AMD EPYC™ 7003 Series CPUs Set New Standard as Highest Performance Server Processor"] (Press release). AMD.com. March 15, 2021. Retrieved April 2021.</ref> |
+ | |||
+ | The codename "Milan" first appeared on AMD roadmaps in 2017. In 2019 a presentation leaked on YouTube and later removed revealed the basic CCD configuration.<ref>Hilgeman, Martin. "Innovator Insights: AMD Epyc for High Performance Computing Workloads". [http://www.hpcadvisorycouncil.com/events/2019/uk-conference/agenda.php HPC-AI conference 2019], September 16, 2019.</ref> The launch of the EPYC 7003 series was announced and a 32-core model demonstrated in a keynote by AMD CEO Lisa Su on January 12, 2021 for [[wikipedia:Consumer Electronics Show|CES]] 2021. | ||
+ | |||
+ | EPYC 7003 processors identify as members of {{amd|CPUID#Family 25 (19h)|AMD CPU Family 19h, Model 01h}} (engineering samples as Model 00h). | ||
+ | |||
+ | == Overview == | ||
+ | "Milan" development focused on microarchitectural improvements, see the {{amd|Zen 3|l=arch}} article for details. The "Milan" <abbr title="System on a Chip">SoC</abbr>s support single and 2-way multiprocessing as well as 2-way multithreading with up to 64 cores and 128 threads per processor. AMD claims up to 15% better performance per cost and 25% more performance in the mid-stack segment compared to the prior generation. | ||
+ | |||
+ | The processors are available in a 4094-contact [[land grid array]] package for {{amd|Socket SP3|l=package}} and backwards compatible with motherboards designed for "Rome" processors (EPYC "Type-1" boards) after a BIOS update. Due to limited [[wikipedia:Non-volatile memory|NVM]] capacity this update may remove support for first generation {{amd|EPYC#7001 Series (Zen)|EPYC 7001}} "{{\\|Naples}}" series CPUs. "Type-0" boards designed for the lower memory and PCIe bus frequencies of "Naples" processors are not supported.<ref name="mln-001">[https://www.amd.com/en/claims/epyc#faq-MLN-001 "AMD EPYC™ Family of Processors Claim Information"]. AMD.com. Retrieved May 2021.</ref> The codename of AMD's Type-1 reference platform is "Ethanol X". | ||
+ | |||
+ | Like the "Rome" series, "Milan" processors are multi-chip modules containing one large I/O die and (as of May 2021) four or eight Core Complex Dies fabricated on a [[TSMC]] advanced [[7 nm process]]. <!-- Singh2020 (doi:10.1109/ISSCC19947.2020.9063113) confirms that Zen 2 is manufactured on a 7 nm process with 6-track cell library (TSMC N7 & H240 HD). Advanced process may refer to TSMC N7P or N7+. Some AMD marketing materials use "7nm+" but this cannot be construed as N7+, see e.g. https://www.anandtech.com/show/15589/amd-clarifies-comments-on-7nm-7nm-for-future-products-euv-not-specified --> The "Rome" CCD integrates two {{amd|Zen 2|l=arch}} Core Complexes (CCX), each providing four CPU cores and a shared 16 MiB L3 cache with 39 cycles average load-to-use latency. In contrast the "Milan" CCD contains a single {{amd|Zen 3|l=arch}} CCX comprising eight CPU cores (the number of usable cores varies by <abbr title="Store Keeping Unit">SKU</abbr>) which share a 32 MiB L3 cache with 46 cycles average latency, doubling the L3 capacity available to one core. | ||
+ | |||
+ | The "Milan" I/O die has largely the same features as the prior generation die fabricated on [[GlobalFoundries]]' [[14_nm_lithography_process|14 nanometer "14LPP" process]]. <!-- AMD did not disclose manufacturing details about the "Milan" sIOD. A diagram in Publ. #57091 "HPC Tuning for EPYC 7003" labels the die as "14nm". --> Apart of the memory controllers and I/O facilites described below it integrates an {{amd|secure processor|AMD Secure Processor}}, a <abbr title="System Management Unit">SMU</abbr>, <abbr title="Real Time Clock">RTC</abbr>, and other functions traditionally found in a separate chipset. | ||
+ | |||
+ | In an interview on March 15, 2021 AMD SVP Forrest Norrod confirmed plans for another server processor series based on the Zen 3 microarchitecture with the codename "Trento". These processors will use a different I/O die with additional coherent {{amd|Infinity Fabric}} links to attach accelerators. They will be used in the exaflop [[wikipedia:Frontier_%28supercomputer%29|Frontier]] supercomputer with nodes comprising one EPYC CPU and four Radeon Instinct MI200 GPUs.<ref>"[https://www.anandtech.com/show/16548/interview-with-amd-forrest-norrod-milan The Tour of Italy with EPYC Milan: Interview with AMD's Forrest Norrod]. anandtech.com. Retrieved May 2021.</ref> "Milan" processors will power the 100 petaflop [[wikipedia:Perlmutter_%28supercomputer%29|Perlmutter]] supercomputer, [https://news.iu.edu/stories/2020/06/iub/releases/01-jetstream-cloud-computing-awarded-nsf-grant.html Jetstream 2], [https://www.rcac.purdue.edu/compute/anvil/ Anvil], and a yet-to-be-named HPE Cray EX system at NSCC Singapore. | ||
+ | |||
+ | === Memory Interface === | ||
+ | The "Milan" I/O die integrates eight [[wikipedia:DDR4 SDRAM|DDR4]] memory controllers (<abbr title="Unified Memory Controller">UMC</abbr>s), two per I/O die quadrant, which achieve data rates from 1333 to 3200 MT/s.<ref name="amd-55898">{{cite techdoc|title=Preliminary Processor Programming Reference (PPR) for AMD Family 19h Model 01h, Revision B1 Processors|url=https://www.amd.com/system/files/TechDocs/55898_pub.zip|publ=AMD|pid=55898|rev=0.35|date=2021-02-05}}</ref> Up to 2 DIMMs per channel are supported.

+ | DIMM0 is the module closer to the CPU. This socket is not present on motherboards which support only one DIMM per channel. | ||
+ | |||
+ | The memory channels are designated A to H. "Rome" and "Milan" processors support 2-, 4-, 8-, and 16-way (on 2P systems) memory interleaving. 4-way mode interleaves the memory channels ABCD and/or EFGH, or CDGH if only these four channels are populated. In contrast to the prior generation CDGH interleaving is supported by all EPYC 7003 <abbr title="Stock Keeping Unit">SKU</abbr>s with 128 MiB L3 cache or less, none having only two <abbr title="Core Complex Die">CCD</abbr>s. Additionally all "Milan" processors support 6-way interleaving if channels B and F remain unpopulated, with a maximum of 256 GiB capacity per channel and restricted to 2 or 4 KiB interleaving size.<ref name="amd-56873"/> The new options enable balanced memory utilization at reduced memory cost when peak memory performance is not required. | ||
+ | |||
+ | With all UMCs implemented in a central I/O die "Rome" and "Milan" processors have a single [[wikipedia:Non-uniform memory access|NUMA]] domain per socket and two NUMA distances on dual-socket platforms. AMD advertised a flatter NUMA domain and reduced inter-core latency since the <abbr title="Core Complex">CCX</abbr>s were pairwise united and the CPU cores in a CCX can exchange data through the shared L3 cache rather than the {{amd|Infinity Fabric|Scalable Data Fabric}} on the I/O die. "Milan" still supports the ''NUMA Nodes Per Socket'' (NPS) and ''<abbr title="Last Level Cache">LLC</abbr>/L3/CCX as NUMA domain'' BIOS setup options. 6-way memory interleaving is only possible with NPS=1.<ref name="amd-56873"/> | ||
+ | |||
+ | Finally an unspecified [[probe filter]] improvement was advertised. | ||
+ | |||
+ | === Input/Output Interfaces === | ||
+ | The "Milan" I/O die integrates eight 16-lane [[wikipedia:PCI Express|PCIe]] Gen 4 (16 GT/s) controllers. Link bifurcation permits configuration of the PCIe lanes as x16, x8, x4, x2, or x1 wide independent links. Each controller supports up to eight PCIe links. On dual-socket systems four, or optionally three, x16 links are repurposed for {{amd|Infinity Fabric|cache coherent inter-socket traffic}}. The raw data rate of these <abbr title="External Global Memory Interconnect, 2nd generation">xGMI-2</abbr> links can reach 18 GT/s. The I/O die also integrates four [[wikipedia:Serial ATA|SATA]] 3.0 (6 Gb/s) controllers which support up to eight links each, multiplexed with the lower eight lanes of four x16 links. [[wikipedia:NVM Express|NVMe]] devices are supported as well. An additional 2-lane PCIe Gen 2 controller powers the WAFL links. One or both of these lanes serve as {{amd|Infinity Fabric#Scalable Control Fabric (SCF)|SCF}} links between sockets and are otherwise available for I/O, e.g. to attach a [[wikipedia:Intelligent Platform Management Interface#Baseboard management controller|BMC]]. In sum up to 128 + 2 PCIe lanes are available per socket and up to 2 × 80 + 2 × 1 = 162 lanes total on dual-socket platforms.<ref name="amd-55898"/> | ||
+ | |||
+ | With the "Milan" series the integrated <abbr title="Input/Output Memory Management Unit">IOMMU</abbr>s were optimized to better handle high-bandwidth devices such as 200 Gbps Ethernet adapters. Support for hotplug surprise removal was brought up to current [[wikipedia:PCI-SIG|PCI-SIG]] implementation guidelines. | ||
+ | |||
+ | Four USB 1.1/2.0/3.1 (10 Gb/s) ports are available on the CPU package, and several low-speed interfaces listed below. | ||

Milan is the codename of AMD's EPYC 7003 series of high-performance microprocessors based on the Zen 3 microarchitecture for single- and dual-socket server platforms. Launched in March 2021 it succeeded the second generation of EPYC processors, the EPYC 7002 "Rome" series.[1]
The codename "Milan" first appeared on AMD roadmaps in 2017. In 2019 a presentation leaked on YouTube and later removed revealed the basic CCD configuration.[2] The launch of the EPYC 7003 series was announced and a 32-core model demonstrated in a keynote by AMD CEO Lisa Su on January 12, 2021 for CES 2021.
EPYC 7003 processors identify as members of AMD CPU Family 19h, Model 01h (engineering samples as Model 00h).
Contents
Overview[edit]
"Milan" development focused on microarchitectural improvements, see the Zen 3 article for details. The "Milan" SoCs support single and 2-way multiprocessing as well as 2-way multithreading with up to 64 cores and 128 threads per processor. AMD claims up to 15% better performance per cost and 25% more performance in the mid-stack segment compared to the prior generation.
The processors are available in a 4094-contact land grid array package for Socket SP3 and backwards compatible with motherboards designed for "Rome" processors (EPYC "Type-1" boards) after a BIOS update. Due to limited NVM capacity this update may remove support for first generation EPYC 7001 "Naples" series CPUs. "Type-0" boards designed for the lower memory and PCIe bus frequencies of "Naples" processors are not supported.[3] The codename of AMD's Type-1 reference platform is "Ethanol X".
Like the "Rome" series, "Milan" processors are multi-chip modules containing one large I/O die and (as of May 2021) four or eight Core Complex Dies fabricated on a TSMC advanced 7 nm process. The "Rome" CCD integrates two Zen 2 Core Complexes (CCX), each providing four CPU cores and a shared 16 MiB L3 cache with 39 cycles average load-to-use latency. In contrast the "Milan" CCD contains a single Zen 3 CCX comprising eight CPU cores (the number of usable cores varies by SKU) which share a 32 MiB L3 cache with 46 cycles average latency, doubling the L3 capacity available to one core.
The "Milan" I/O die has largely the same features as the prior generation die fabricated on GlobalFoundries' 14 nanometer "14LPP" process. Apart of the memory controllers and I/O facilites described below it integrates an AMD Secure Processor, a SMU, RTC, and other functions traditionally found in a separate chipset.
In an interview on March 15, 2021 AMD SVP Forrest Norrod confirmed plans for another server processor series based on the Zen 3 microarchitecture with the codename "Trento". These processors will use a different I/O die with additional coherent Infinity Fabric links to attach accelerators. They will be used in the exaflop Frontier supercomputer with nodes comprising one EPYC CPU and four Radeon Instinct MI200 GPUs.[4] "Milan" processors will power the 100 petaflop Perlmutter supercomputer, Jetstream 2, Anvil, and a yet-to-be-named HPE Cray EX system at NSCC Singapore.
Memory Interface[edit]
The "Milan" I/O die integrates eight DDR4 memory controllers (UMCs), two per I/O die quadrant, which achieve data rates from 1333 to 3200 MT/s.[5] Up to 2 DIMMs per channel are supported. The Infinity Fabric and memory bus clock can be coupled to slightly reduce the memory latency, "Milan" processors permit this up to 1600 MHz matching DDR4-3200 memory.[6] The memory controllers support ECC memory and the following DIMM types:[7]
- SR/DR RDIMM built with x4 and x8 DDR4 devices
- 4R/8R LRDIMM built with x4 devices (4DR, 2S2R, 2S4R)
- 4R/8R 3DS DIMM built with x4 devices (2S2R, 2S4R)
- NVDIMM-N (DRAM with NVM backup)
The maximum total memory capacity is 4 TiB per socket using 16 LRDIMMs or 3DS DIMMs of 256 GiB capacity.

DIMM0 is the module closer to the CPU. This socket is not present on motherboards which support only one DIMM per channel.
The memory channels are designated A to H. "Rome" and "Milan" processors support 2-, 4-, 8-, and 16-way (on 2P systems) memory interleaving. 4-way mode interleaves the memory channels ABCD and/or EFGH, or CDGH if only these four channels are populated. In contrast to the prior generation CDGH interleaving is supported by all EPYC 7003 SKUs with 128 MiB L3 cache or less, none having only two CCDs. Additionally all "Milan" processors support 6-way interleaving if channels B and F remain unpopulated, with a maximum of 256 GiB capacity per channel and restricted to 2 or 4 KiB interleaving size.[7] The new options enable balanced memory utilization at reduced memory cost when peak memory performance is not required.
With all UMCs implemented in a central I/O die "Rome" and "Milan" processors have a single NUMA domain per socket and two NUMA distances on dual-socket platforms. AMD advertised a flatter NUMA domain and reduced inter-core latency since the CCXs were pairwise united and the CPU cores in a CCX can exchange data through the shared L3 cache rather than the Scalable Data Fabric on the I/O die. "Milan" still supports the NUMA Nodes Per Socket (NPS) and LLC/L3/CCX as NUMA domain BIOS setup options. 6-way memory interleaving is only possible with NPS=1.[7]
Finally an unspecified probe filter improvement was advertised.
Input/Output Interfaces[edit]
The "Milan" I/O die integrates eight 16-lane PCIe Gen 4 (16 GT/s) controllers. Link bifurcation permits configuration of the PCIe lanes as x16, x8, x4, x2, or x1 wide independent links. Each controller supports up to eight PCIe links. On dual-socket systems four, or optionally three, x16 links are repurposed for cache coherent inter-socket traffic. The raw data rate of these xGMI-2 links can reach 18 GT/s. The I/O die also integrates four SATA 3.0 (6 Gb/s) controllers which support up to eight links each, multiplexed with the lower eight lanes of four x16 links. NVMe devices are supported as well. An additional 2-lane PCIe Gen 2 controller powers the WAFL links. One or both of these lanes serve as SCF links between sockets and are otherwise available for I/O, e.g. to attach a BMC. In sum up to 128 + 2 PCIe lanes are available per socket and up to 2 × 80 + 2 × 1 = 162 lanes total on dual-socket platforms.[5]
With the "Milan" series the integrated IOMMUs were optimized to better handle high-bandwidth devices such as 200 Gbps Ethernet adapters. Support for hotplug surprise removal was brought up to current PCI-SIG implementation guidelines.
Four USB 1.1/2.0/3.1 (10 Gb/s) ports are available on the CPU package, and several low-speed interfaces listed below.
